Research Abstract

Necrotic cell death is mediated through the mitochondrial permeability transition(MPT) dependent on cyclophillin D(CypD). The aim in this study is to clarify the intracellular signalling mechanism of the cardiomyocyte cell death and progression of heart failure on the hypothesis that the signal crosstalk between apoptotic and necrotic pathways exists. We took note of CypD and apoptosis signal-regulating kinase 1(ASK1). ASK1 can bind to CypD. ASK1 is related to the CypD mediated through the MPT. The crosstalk between ASK1 and CypD may be involved in progression of heart failure.
